ABN Lookup
Verify any ABN before sending a letter of demand. Data sourced directly from the Australian Business Register (ABR).
You can enter with or without spaces.
Why verify an ABN?
- Confirm the debtor is a registered Australian business
- Ensure the business name on your invoice matches the ABR
- Detect cancelled or deregistered entities before sending a formal demand
- Required on a formal letter of demand when the debtor is a business, to establish credibility
A registered ABN doesn't guarantee a debtor can pay — for context on which industries and companies are the slowest and riskiest payers in Australia, see the 2026 Australian Debt Collection Report.
